  • Patent number: 7490617
    Abstract: A step-extending device is adapted for use in association with a walker to ascend or descend a stairway. The step-extending device may employ a first base and a second base, each of which is adapted to receive legs of a walker upon respective upper surfaces. The device may be used in connection with a frame that connects the first and second bases to each other. A cross member connects first and second bases. A frame includes one or more upright members with handles adapted for grasping and moving the step-extending device from one stair to another stair during use. The height of each of the first and second support bases is adjusted to approximate the height of stairs upon a stairway, so that stairs of essentially any height may be accommodated.
